This patch prepares the namespace support for layer 4 protocol trackers. Basically, this modifies the following interfaces: * nf_ct_[un]register_sysctl * nf_conntrack_l4proto_[un]register to include the namespace parameter. We still use init_net in this patch to prepare the ground for follow-up patches for each layer 4 protocol tracker. We add a new net_id field to struct nf_conntrack_l4proto that is used to store the pernet_operations id for each layer 4 protocol tracker. Note that AF_INET6's protocols do not need to do sysctl compat. Thus, we only register compat sysctl when l4proto.l3proto != AF_INET6. Acked-by: Eric W.
